研究概览
简要总结
The investigator will collect data on penile and glans size by age, weight and ethnicity in both patients undergoing routine urological surgery and hypospadias surgery.
详细描述
After obtaining informed consent , the investigator will measure stretched penile length and glans size in 3 dimensions (length, width, height) in the office on patients with hypospadias, as well as at the time of operation, after the induction of anesthesia. Patients undergoing hypospadias surgery will be considered study subjects. If the patient was given pre-operative testosterone as part of the current standard of care, this will be noted and the measurements taken at each pre-operative office visit will be recorded. The investigator will also record corrected age, weight in kilograms and ethnicity as identified by the family.
Control patients will be those male patients undergoing non-hypospadias urological surgery (hernia repair, orchiopexy, circumcision, re-circumcision) with a normal penis, the investigator will perform a single intra-operative measurement of the same glans and penile variables after induction of anesthesia and prior to the start of their genital surgery. Again, age, weight and ethnicity will be recorded.
